Critical Reasoning

Critical Reasoning

Dr. Denise Grant’s recent study states that young children who have a low white blood
cell count have the tendency to score lower on mental health diagnostics than do children with normal or high white blood cell counts. Dr. Grant inferred from these findings that white blood cells not only aid the body in
fighting off physical illnesses, but mental illnesses as well.

Which of the following is an assumption on which the argument above is based?

(A) Psychological treatment of mental illness in young children is not as effective as is drug therapy.
(B) Mental illness does not cause the white blood cell count of young children to decrease.
(C) A high white blood cell count protects against mental illness in young children better than a normal white blood cell count does.
(D) Young children with high white blood cell counts cannot develop mental illness.
(E) Mental illness is analogous to physical illness in the way it affects the body.
